TOE-IN
Standard value:
Ok3 mm (Of.12 in.)
1. Adjust the toe-in by undoing the clips and turning the left and right tie rod turnbuckles by the same amount (in
opposite directions).
2. The toe will move out as the left turnbuckle
is turned
toward the front of the vehicle and the right turnbuckle is
turned toward the rear of the vehicle.
3.For each half turn of the left and right tie rods, the toe-in will
be adjusted by 6 mm
(.24 in.).
4.After making the adjustments, use a turning radius gage to confirm that the steering wheel turning angle is within the
standard value range. (Refer to GROUP 37A
POWER
STEERING-Service Adjustment Procedures.)
WHEEL BEARING ADJUSTMENT

Bearing preload is pre-set to the specified value by design and
therefore can not be adjusted.
ALARM LIGHT CHECK
MPFNAC
The bulb of the alarm light can be checked by whether or not it is illuminated for approximately 0.5 of a second by the
Electronic Control Suspension control unit when the ignition
key is turned ON, and, after the engine is started.
SYSTEM CHECKING BY USING ALARM LIGHT 1. After checking the alarm light bulb to be sure it has not failed, let the engine idle for approximately 4 minutes ormore to check to be sure that the alarm light does not
illuminate.
2.While the alarm light is on, connect the scan tool or a volt- meter to the data link connector of the wiring harness and
check the on-board diagnostic output code.
3. Use the output pattern for troubleshooting (Refer to
P.33B-11.)
NOTE*
Although the alarm light illuminates under the following
circumstances, there is no actual malfunction if, after the
following procedures have been followed and then the
alarm light does not illuminate after waiting about four
minutes or more.
1. When there is an overload Stop the engine, unload the cargo, and then restart the
engine.
2.When the vehicle is stopped (with the engine running)
on a steep hill or slope.Move the vehicle to a horizontal place and stop; then
stop the engine and restart it.

1. Move the wheels to the straight-ahead position.
2. Start the engine.
3. Set to the AUTO mode (normal vehicle height).
4. Press the control mode switches, and check the illumina-
tion of the damping force level indicator lights when themodes shown below are selected.In addition, check to be sure that there is a difference of
the damping force for each control mode when the vehicle
is moved up and down at a rate of twice per second.

CHECKING THE ANTI-ROLLING FUNCTION
1. Move the wheels to the straight-ahead position.
2. Turn the ignition key to ON.
3. When simulated vehicle-speed signals of 35 km/h (22 mph) or higher are input and the steering wheel is turned
45” or more, the damping force characteristic indicator light will change to MEDIUM or HARD, depending on the
speed at which the steering wheel is turned. Check to be sure that this sensitivity increases (for each
control mode) as the vehicle speed increases.
NOTE
The damping force characteristic will return to its previous
level about tow seconds*4
after the change to MEDIUM or
HARD.

SERVICE POINTS OF REMOVAL
1. REMOVAL OF THROTTLE POSITION SENSOR
Disconnect the harness connector, then remove the
throttle position sensor from the throttle body.
2.REMOVAL OF STEERING WHEEL ANGULAR-VELOCITY
SENSOR
Remove the pin terminal from the column switch connec-
tor, then remove the steering wheel angular-velocity sensor from the column switch.
Caution
1.The steering wheel angular-velocity sensor utilizes a
photo coupler and care should be paid to ensure
that no dust or grease are allowed to come into contact with it.
2. Be careful and ensure that the column switch side
slit panel is not bent nor oil allowed to come into
contact with it.
3. REMOVAL OF
G SENSOR
Disconnect the connection of the harness connector, and
then remove the
G sensor.
Cautio
n
When removing the
G sensor, take care not to drop it or
subject it to severe impact.
INSPECTION For information concerning the procedures for checking each
sensor, refer to the service adjustment procedures section
and to the troubleshooting guide.

SERVICE BRAKES - Anti-lock Braking System Troubleshooting35-15
ANTI-LOCK BRAKING SYSTEM
TROUBLESHOOTINGM35EElAE
PARTICULAR CHARACTERISTICS OF
THE ANTI-LOCK BRAKING SYSTEM
Models equipped with the anti-lock braking system
(A.B.S.) may exhibit one or more of the following
characteristics from time to time, but none of these
is abnormal.
(1)
(2)
A pulsing feeling in the brake pedal, or vibration
of the body or the steering wheel, when the
anti-lock braking system is activated by sudden
braking or by braking on a slippery road surface.
Actually, this phenomenon is an indication that
the anti-lock braking system is functioning nor-
mally.
When the vehicle speed reaches approximately
6 km/h (4 mph) after the engine is started and
the vehicle starts off (for the first time), awhining motor noise may be heard from the
engine compartment if the vehicle is traveling in
a quiet place. This noise is simply the result of a
self-check being made of the anti-lock braking
system operation.
TROUBLESHOOTING METHODS
Problems related to the anti-lock braking system
(A.B.S.) can be classified into two general categor-
ies: problems in the electrical system and those in
the hydraulic system. For problems in the electrical system, the on-board
diagnostic is built into the electronic control unit
(E.C.U.) causing the A.B.S. warning light to illuminate
as a warning to the driver. In this instance, checks
can be made by using the scan tool and oscillo-
scope.
Problems in the hydraulic system (poor braking,
etc.) can be located in the same way as for ordinary
brakes. There is, however, the necessity to check to
determine whether the problem is related to ordi-
nary brake components or to the components re-
lated to the A.B.S. To make this check, use the scan
tool.
HOW TO USE THE TROUBLESHOOTING
FLOW CHART
(1) Using the flow chart, check the ABS warning
light light-up sequence. Read the diagnostic
trouble codes and check the condition of bra-
king operation.
(2) Following the check chart listed in the remedy
column, perform the checks. There are [Expla- nation] and [Hint] in each check chart. Refer to
them when troubleshooting.
